Reasons to get rush and bust on BrutaliTune

Ultimate Performance with gas restriction adjustment option, you can set the optimum exhaust backpressure is known as the key of maximum performance. BrutaliTune is proven to deliver the most in power with tunable straight through Triple Perf Tube Design. BrutaliTune gives you more rideable HP, improves torque, acceleration and smoothes out throttle response.

Premium quality raw materials.

End cap, mid pipe and intake tube and internal components are crafted of the highest grade SS304 stainless steel inside and out. They resist rain, water, salt water, acids and high temperature in all types of terrain. BrutaliTune is a durable and reliable mechanical muffler sustaining even the harshest conditions. The Chrome Plated end cap is forged out of high quality brass. It features spark arrestor. This cap will never ever stain or lose its chrome gleam. (Frequent maintenance required.)

Why to install a spark arrestor?

Spark arrestors (also known as flame arresters) are designed for preventing the risk of fire because of the ignition of flammable materials, caused by spark emissions from the exhausts. The risk of fire caused by exhaust sparks is so high that access too many sites is barred unless engines are fitted with spark arrestors. Spark arrestors are most commonly used in conjunction with internal combustion engines as well as improving safety within fireplaces for instance. Often, a spark arrestor mimics a net fashioned from tightly interwoven wire gauze built to resist piece of ash, sparks, etc. Magnum Spark arrestor is sturdy and maintenance free, it will last as long as you own your exhaust. Our screen type spark arrestors integrated into BrutaliTune Exhaust cap, make these mufflers absolutely safe. H3Backfires in general/H3 Backfire, also called as lean misfire on deceleration is primarily attributed to an improperly adjusted or tuned engine, ignition or an exhaust / exhaust system with non-optimal gas restriction. If you are struggling with backfires, check your spark plugs and the ignition advance to verify the tune-up is correct. The plugs should be a light tan (deer brown) in color if worked properly. If all OK you should be suspicious the problem is at the exhaust. In many cases, misfire is an indication that the exhaust is too free flowing. Pipes might be too large in diameter or muffler's volume is higher than required for the engine configuration you have. BrutaliTune Exhaust installed on factory motorcycle does not produce backfires in case of appropriate restriction adjustment. Thanks to its variable-cross section core, you can tune that optimal power-band will fit your performance needs and riding style. Misfire is not uncommon on racing setups though, or on motorcycles run on extremely rich mixture at lower air / fuel ratio than 13:00.

This tunable performance muffler is not Bolt-on to your Yamaha WK125 RR Carb. It installs with Weld-on universal installation that might require exhaust modification. Prior to the purchase please collate the dimensions of your factory exhaust muffler with the BrutaliTune specifications or feel free to contact our Product Specialists 7 days a week.

Place BrutaliTune Exhaust up beside the factory muffler. Allocate the welding line to a feasible position and mark at which diameter you will need to cut the cone inlet.

Cut the cone inlet where marked.

Remove the factory pipe and cut the piping where necessary. Use a handsaw, power saw, reciprocating saw or angle grinder. Do not create any stricture towards the exhaust tail. The BrutaliTune's inlet has to be a bit larger or equivalent to the factory pipe's diameter.

Spot-weld on the exhaust and recheck its position. Use a MIG, TIG or Flux welder.

Weld around the connection.

Crank the engine and check for leaks.

Find one or two fixtures for the exhaust clamps.

Bend the straight sheets around the exhaust body creating a clamp.

Use bolts and nuts for fixing.

Sound Performance Tuning

Remove the exhaust cap.

Put on either rotary disc and secure the wing-nut on the thread applying finger power.

Check Magnum factory recommendations and consult the diagram that appears on the instructions or experiment by rotating the disc to either direction.

Rev the engine repetitively and test the exhaust sound by making test rides to adjust the peak performance throughout the RPM range. Cap not required for tests.

When the best performance and throttle response is reached, secure the wing-nut on the center bolt with pliers. Put the spring washer underneath the wing-nut.

Slide the cap on the mid pipe’s end.

Secure the cap with wing bolts.

Notes

In theory, the larger the exhaust cross section is opened, the less restriction is implied, which evokes a higher din. However the optimum gas restriction cannot be determined in principle.

There is no recipe or formula which could precisely guide you through how to adjust the discs.

We recommend that you to start with an intermediate masking of cross flow area, say half covered, half open.

Never close the cross flow area completely!

This tunable performance muffler is not Bolt-on to your Yamaha WK125 RR Carb. It installs with Weld-on universal installation that might require exhaust modification. Prior to the purchase please collate the dimensions of your factory exhaust muffler with the BrutaliTune specifications or feel free to contact our Product Specialists 7 days a week.

Never close the cross flow area totally!

This exhaust does not work on 2-stroke engines.

Dual exhaust requires two units.

On fuel injected engines fuel trim remap is recommended when replacing stock restrictive mufflers. You may get a sneak peek at our Fuel Controllers .

On emission controlled motorcycles fitted with exhaust oxygen sensor, aftermarket pipe triggers the check engine light, accordingly you have to wire up an oxygen sensor simulator.

Never close the cross flow area totally!

Claims correlate to factory condition engine.

Regardless of manufacturer, high flow pipes are not capable to deliver such low noise emission as factory exhaust produces. You cannot find such disc layout would warrant factory exhaust sound. Expect louder but quality sound by all means.

Warranty voids if vehicle is used for racing.

This exhaust is an off-road part. BrutaliTune is not CARB Approved, and is never to be used on Pollution Controlled Vehicles or on Public Highways in those states and countries where emission control law is in effect.

noticeable increase in the lower RPM's.

As earlier reviewers have claimed, their weld-on is relatively easy to install and when compared to stock horses has a noticeable increase in the lower RPM's. It's fairly meaty sounding, and I am bound with loudest disk setup it broke the 100 decibel upper limit. Bottom line it well worth the money and I didn’t regret I forked over the money to buy this pipe.

satisfied with both power and note

When I stumbled across this pipe I was concerned with avoiding amplification of stock exhaust note. I’m very finicky when it comes to install an aftermarket part on my bike. After 5 hours of tuning I reached optimum disk setup that ensured nice rumble even when I was heavy on the throttle. In parallel with disk rotation mid and low end torque is changing. Finally I could adjust a point I am satisfied with both power and note. Free shipping is generous but I’d have paid extra if it came with expedited postage. Overall I am a happy buyer.

Grunts and pulls much harder

Can't believe the difference! Easily installed on 350 EXC with stock head pipe and all the common performance mods. Notably improved bottom end power. Grunts and pulls much harder down low in the rev range even in deep sand. You can pull a gear higher in most situations and is harder to stall in corners. Awesome deep exhaust sound, it’s not too loud when adjust the disks. If you ride in areas where "noise" is a problem, then turn or change disk. Highly recommended.

this hi-flo pipe rocks put it on my new X8 that came with restricted stock exhaust, didn’t want to keep it like that but this pipe was a bit difficult to convert it over muffler sounds great when you open up the throttle unprecedented performance throghout rpm range tech team works decently

ton of top that revs to the moon

i put this tuneable pipe on my miler 125cc bike a while it did give me ton of top that revs to the moon an back compared to stock it takes away the hit in the middle that i love about my miler… sound this pipe emits is amazing if you love to rev it out then this is the pipe of your taste.
